difference between Company, Limited, and Corporation

http://en.wikipedia.org/wiki/Corporation
In most countries, corporate names include the term "Corporation", or an abbreviation that denotes the corporate status of the entity.
Certain jurisdictions do not allow the use of the word "company" alone to denote corporate status, since the word "company" may refer to a partnership or to a sole proprietorship.

Many Corporations operate under a fictition name: for example "Microsoft Corporation" operates under the fictious name "Microsoft".

http://en.wikipedia.org/wiki/Limited_liability_company
"Limited" designates something as being an LLC (limited Liability Company): In that respect, it is similar to a corporation, and is often a more flexible form of ownership, especially suitable for smaller companies with a limited number of owners. Unlike a regular corporation, however, a limited liability company with one member may be treated as a disregarded entity, so the member is often singled-out as a person performing the actions of the LLC.

So, just use the business's actual name or fictition name. Don't try adding words to a company's name. So, refer to Microsoft either as "Microsoft" (the fictious name) or "Microsoft Corporation", but don't ever use "Microsoft Company Corporation". A business has to fill out certain forms if it wants to operate under a fictitious name--it's usually a shorter name without words like "Company" or "Corporation or "LLC" or "Inc." etc.

What is the simple difference between Limited and Corporation? Is this has to do something with stock market? Suppose there was a certain company whose name is James Corporation. Can we write James Company Corporation? Is there some difference between Company and Corporation? Then the name changes to James Company Limited. What is the purpose of changing the name?

What is the difference between Company limited and Corporation??

In case if there is no difference, then why we see companies by names called Company Limited and  Corporation.
